This may be working. Once banks were closed, it appears there may be a majority for a "yes" on the referendum.

What does Tsipras want? That is almost impossible to gauge and is the biggest problem. He says he wants to stay in the euro, but no one believes it. He wants to keep his job, but it's not clear what path he can take to achieve that. He can still stir the pot with new ideas like a referendum, but he is getting boxed in quickly.

That makes him very dangerous. There will be more maneuvering before Sunday.
